【Example】

Embodiment 1 FIG. FIG. 1 shows a basic configuration diagram relating to operation display in a train operation management system according to one embodiment of the present invention. Reference numeral 13 denotes an operation state and the like displayed on a conventional operation display device 2 in accordance with the movement of a train. A video projector as a display device for displaying an ITV screen in a superimposed manner. For example, two video projectors 1 and 2 are connected if necessary according to the length of a route to be displayed or the number of stations. An operation display controller 14 is connected to each video projector 13. The operation display controller 14 has a video composite NTSC and RGB input interfaces as superimposed inputs, and can input not only an ITV camera 15 input, a tuner 16 input, but also a video deck, a laser disk, and the like. (Frames / second) can be displayed on the X window. Also, it has a function of storing frames of a moving image on a memory at an arbitrary interval and displaying the frames later on.

Normally, the video projector 13 displays an operation status screen (computer screen) which is an RGB input from the operation display controller 14 (engineering workstation). On the operation status screen, a schematic wiring diagram, platform, station name, train number display window on the platform and between stations, etc. are displayed on the operation status screen, and according to the movement of the train, the train number in the train number display window is displayed. The shift and the color change due to the train location on the wiring schematic (non-location; blue, track configuration; yellow, location; red) are performed. When the ITV screen is displayed in superimposition in accordance with the movement of the train, the window is displayed at predetermined coordinates on the operation status screen. FIG. 2 shows an example of a video projector display screen. In this example, since the train has entered the approaching section of Station B, the color change of the route and the like and the IT
The V screen is displayed in superimpose.

Next, the processing flow of the operation display controller 14 will be described with reference to the flowchart of FIG. Normally, the operation display controller 14 obtains the display information of the station (train position, traffic signal, track state, etc.) from the relay section of the station via the transmission device, and adds a train number unique to the train to the video projector. 13 and displays an operation status screen, which is a computer screen, as a base screen (S1). If the train is located in the approaching section of a station (usually the third track circuit outside the on-site traffic signal) due to a change in the location of the train (track circuit falls) (if it is present in S2), it is installed on the platform of the station. ITV camera 15
Is displayed near the display of the station by superimposition (S3).
When none of the trains has entered the approaching section of the station (when there is no train in S2), only the operation status screen is displayed. Similarly, when the train departs from a certain station and enters the first track circuit inside the departure signal (when S4 is present), the ITV screen of the station already displayed is deleted (S4).
5). As a result, only the operation status screen is displayed on the video projector 13 (S1). Further, when the operation commander requests information from the tuner 16 using a keyboard or the like (if yes in S6), the tuner screen is displayed in superimposed (S7). Information from the tuner 16 includes weather information, news, and the like, which have a large effect on train operation.

Similarly, when the input of the erasure of the tuner screen is input from the keyboard or the like (if yes in S8), the tuner screen already displayed is erased (S9). As a result, only the operation status screen is displayed on the video projector 13 (S1). The frames of the moving image are stored in the memory at an arbitrary interval for each time, and when a playback is input with a specified time for verification of a diamond disorder, a weather abnormality, etc. The time frame is played back and displayed (S11). Further, when a hard copy is requested (when it is determined in S12), a hard copy can be output. When the deletion of the playback display is input (when the answer is YES in S13), the playback display is deleted and only the operation status screen as the base screen is displayed (S1). Note that the above S4, S6, S8, S10, S1
2. If the determination in S13 is "NO", the screen currently displayed is not changed. As described above, since the ITV screen is automatically displayed on the operation status screen in a superimposed manner according to the train location, the ITV monitor CRT is displayed.
Not only can the ITV screen be confirmed without the need, but also the switching operation of the ITV screen by the commander becomes unnecessary.

Embodiment 2 FIG. In the first embodiment, the computer screen is combined with the ITV screen and the tuner screen by the superimpose input interface of the operation display controller. However, the superimpose input of the operation display controller is not provided, and the external display is not provided as shown in FIG. May be provided with a multimedia scan converter. The multimedia scan converter is a synthesizing device that displays a video camera, VTR, and ITV images on a display of a workstation in real time as moving images by cutting windows. This multimedia scan converter uses the RGB input from the operation display controller 14 as a base signal and uses the NTS from the ITV camera 15 and the tuner 16 as a base signal.
The C input is synthesized and the RGB output is performed to the video projector 13. As described above, similarly to the first embodiment, the ITV screen and the tuner screen are automatically displayed on the computer screen of the operation display controller 14 in the video projector 13 in a superimposed manner in accordance with the movement of the train.

Embodiment 3 FIG. The length of the cable between the devices may be long depending on the environment where the devices are installed, which may adversely affect the image quality. Assuming such a case, the basic configuration of the first and second embodiments is applied to the distributor with the cable compensator. May be provided. The divider with compensator distributes the output signal of one device to a plurality of devices while preventing signal level attenuation. The configuration diagram is shown in FIG. This not only eliminates the problem of signal attenuation, but also enhances the scalability of each terminal such as display on another display or hard copy. For example, even when the ITV screen is conventionally switched in a maintenance terminal room or the like that is far away from the operation instruction room, the ITV screen is automatically switched in accordance with the movement of the train.

Embodiment 4 FIG. In the first to third embodiments, a video projector is used as the operation display device. However, instead of the video projector, the operation display controller C which is an engineering workstation is used.
RT may be the main display device. In this case, as in the above embodiment, the ITV screen or the like may be displayed in a superimposed manner. However, if the display screen is small and cannot be seen clearly, the entire screen is switched from the operation status screen to the ITV screen instead of the superimposed screen. What is necessary is just to switch. This eliminates the need for a video projector and makes the apparatus cheaper.

Embodiment 5 FIG. In the first to third embodiments, the ITV screen is superimposed on the computer screen. However, in this configuration, several ITV monitors CRT are installed on the video projector, and the superimposition of a certain station is performed. If the pause ITV screen is enlarged and displayed on the ITV monitor CRT, the details of the ITV screen can be confirmed. In this case, the superimposed display is preferably performed on the video projector at the same timing as in the first embodiment, and the display is performed on the ITV monitor CRT at a certain fixed period. As a result, the number of ITV monitor CRTs, which previously required 20 or more, can be reduced to several, and the operation management operation can be performed efficiently.

[0028]

Since the present invention is configured as described above, it has the following effects.

[0029]

According to the present invention, an operation status screen is output and a plurality of ITs are output.
The ITV screen shot by the V-camera is matched to the train movement.

By doing so, the operation management work can be performed efficiently.

Further, since the switched ITV screen is displayed in a part of the operation status screen of the video projector in a superimposed manner, the ITV monitor CRT becomes unnecessary and the apparatus can be inexpensive.

In addition, the ITV screen and the other screens are taken together.
Plug-in multimedia scan converter
Since the TV screen is displayed in a superimposed manner, the ITV screen can be switched more easily.

Further, the signal level of the input signal is attenuated.
And a distributor with a cable compensator for distributing the output signal to a plurality of components increases the expandability of the system.

Further, since the CRT of the operation display controller is used as the display device, the cost of the device can be reduced.

Further, since the output to the ITV monitor CRT is performed together with the superimposed display of the ITV screen, a more detailed operation management operation becomes possible.

In addition, the operation display controller displays an ITV screen photographed by an ITV camera at the station from the moment the train is on the approaching section of the station until the train enters the first track circuit inside the departure signal of the station. Is displayed on the display device, so that the operation status can be easily grasped.
